Group 1 - The core viewpoint of the article highlights the trend of increasing battery capacities in range-extended electric vehicles (REEVs) in the Chinese market, with a clear stratification in battery capacities across different price segments by 2025 [1][11]. - The mainstream battery capacity for entry and mid-range REEVs is concentrated between 28-40 kWh, corresponding to a pure electric range of 200-300 km [3][10]. - High-end REEVs are expected to feature battery capacities of 60-80 kWh, with some models exceeding 80 kWh, aligning closely with or surpassing mainstream pure electric vehicles [2][8]. Group 2 - The Ideal L series models, including L7, L8, and L9, are set to have a main battery capacity of 52.3 kWh, making them a dominant configuration in the mid-to-high-end market [4]. - The Wanjie M series models, such as M7, M8, and M9, will have main battery capacities ranging from 42 to 53.4 kWh, with higher configurations reaching up to 53.4 kWh [4]. - The Xiaopeng X9 features a battery capacity of 63.3 kWh, while the Zhiji LS6 and the Zunji S800 have capacities of 66 kWh and 65 kWh respectively, both offering a pure electric range exceeding 450 km [5][6]. Group 3 - The industry is witnessing a trend towards "increased capacity big batteries," with high-end models' battery capacities now comparable to mainstream pure electric vehicles, such as the 80.3 kWh battery in the Leap D19 [8]. - The competition in the high-end market is focusing on "pure electric first," with range extenders serving as a backup solution, leading to a consensus on the need for large capacity and long range [9]. - By 2025, most new REEV products are expected to standardize battery capacities of 60 kWh and above, with high-end models likely to approach or exceed those of some pure electric vehicles [9][12].
